Abstract

A light emitting diode display module includes a circuit board with a plurality of light emitting diodes, a bracket with a plurality of grids, and a light conductive panel that includes a plurality of light conductive portions in the grids and in a one-to-one correspondence with the plurality of light emitting diodes, a height of one of the light conductive portions being lower than a height of another light conductive portion, a covering film arranged on the surface of the light conductive panel, and light transmitting portions for displaying information on the covering film at positions corresponding with the plurality of light conductive portions.

Claims

1-5. -5. (canceled)

6. A light emitting diode display module, comprising:

a circuit board with a plurality of light emitting diodes;

a bracket with a plurality of grids; and

a light conductive panel comprising;

a plurality of light conductive portions in the grids and in a one-to-one correspondence with the plurality of light emitting diodes, a height of one of the light conductive portions being lower than a height of another light conductive portion;

a covering film arranged on the surface of said light conductive panel; and

light transmitting portions for displaying information on the covering film at positions corresponding with the plurality of light conductive portions.

7. The light emitting diode display module of claim 6, wherein the height of the light conductive portion is ½

to ⅔

of the height of the another light conductive portion.

8. A washing machine comprising:

a circuit board with a plurality of light emitting diodes;

a bracket with a plurality of grids;

a light conductive panel comprising;

a plurality of light conductive portions in the grids and in a one-to-one correspondence with the plurality of light emitting diodes, a height of one of the light conductive portions being lower than a height of another light conductive portion;

a covering film arranged on the surface of said light conductive panel; and

light transmitting portions for displaying information on the covering film at positions corresponding with the plurality of light conductive portions, wherein the information corresponding to the another light conductive portion comprises time information of the washing machine, and the information corresponding to the one of the light conductive portions is other information.

9. The washing machine of claim 8, wherein the light emitting diodes corresponding to said lower light conductive portion forms a seven-segment numeric tube.

10. The washing machine of claim 8, wherein the information displayed through said light-transmitting portions by the light emitting diodes corresponding to the higher light conductive portions includes information indicating temperature, rotating speed, and operation status.
